K&F STAR Gwiazdka 2-in-1 Filter set for 52 mm lenses — 4-point and 8-point star effects (KF01.2327)

The K&F STAR Gwiazdka 2-in-1 Filter set for 52 mm lenses provides two selectable starburst effects in a single screw-on accessory. Designed for lenses with a 52 mm filter thread, this optical filter creates either a 4-point or an 8-point star effect by diffracting bright light sources in the scene. It is intended to enhance highlights and specular reflections directly in-camera, reducing the need for post-processing when shooting night scenes, cityscapes, portraits with catchlights or other creative compositions.

Advantages

This screw-on filter set offers on-demand switching between two star patterns without removing or replacing filters, enabling rapid creative adjustments in the field. The optical surface is engineered to produce consistent diffraction across light sources, giving predictable star shapes on streetlights, car headlights and reflective highlights. The compact, threaded design maintains the normal working distance of the lens and does not require additional mounting hardware.

Suitable for

• Night and cityscape photography to emphasize point light sources
• Portraits where enhanced catchlights improve subject appearance
• Creative and long-exposure photography with visible highlights
• Street and event photography for adding visual interest to specular reflections

Key specifications

• Filter thread size: 52 mm screw-on
• Two selectable star patterns: 4-point and 8-point
• Optical performance: diffraction-based starburst effect for point light sources
• Construction: low-profile threaded mount compatible with 52 mm lens barrels
• Intended use: in-camera creative effect without digital editing

How to use

Screw the filter onto a lens with a 52 mm thread until secure, then frame the composition so that bright light sources or specular highlights are within the image. Select the desired star pattern according to the subject and lighting; images will show the corresponding 4-point or 8-point diffraction around intense highlights. Adjust exposure and aperture as needed — smaller apertures tend to sharpen and define star points, while wider apertures will soften the effect. Remove the filter when the star effect is not required.

Usage recommendations

For clearer and stronger starbursts, use the filter with distinct point light sources such as street lamps, holiday lights or reflections on wet surfaces. Combine moderate ISO and stable support (tripod) when shooting low-light scenes to retain image detail while capturing the star effect. Avoid stacking multiple filters unless necessary, as additional glass may weaken contrast.
